Make sure your safety data sheets are kept protected and within reach with the Avery UltraDuty safety data sheet binder kit. This easy SDS binder starter pack includes a 3" poly SDS 3 ring binder with chain, heavy-duty preprinted plastic A-Z binder dividers and 25 sheet protectors that secure with top flaps. The industrial-grade 3 ring binder is built with tough yet flexible plastic designed to withstand damage from water, abrasion and chemicals such as heptane, isopropyl alcohol cleaner, sodium hydroxide and more. The durable front and back covers are wide enough to fully cover the dividers and sheet protectors for a cleaner appearance. A 36" long chain is also included with a metal clasp in order to keep your material safety data sheets close to your SDS binder holder or rack while making sure that they stay in the same spot. The metal chain hooks into a reinforced hole in the binder spine in order to avoid damage to the binder rings and locking mechanism. An elastic strap is also attached that hooks onto the front cover to keep the binder securely closed. The 3" slant rings can hold up to 735 sheets.
